a carnival ride is made so that at a certain point the floor can be lowered and the people inside dont fall. if this carnival ride has 2.0 m radius and rotates 1.1 times per second: a) find the speed of the ride.
B) find the centripetal acceleration of a rider
C) what produces this acceleration?
D) when the floor drops down, the rider's weight is balanced by friction. What coefficient of friction in needed to keep the riders from slipping?
